2024-08-07jffs2: Convert jffs2_write_end() to use a folioMatthew Wilcox (Oracle)
Convert the passed page to a folio and operate on that. Replaces six calls to compound_head() with one. Also use kmap_local instead of kmap.

2024-08-07fuse: Convert fuse_write_begin() to use a folioMatthew Wilcox (Oracle)
Fetch a folio from the page cache instead of a page and use it throughout removing several calls to compound_head() and supporting large folios (in this function). We still have to convert back to a page for calling internal fuse functions, but hopefully they will be converted soon.

It's hard to return a directory entry from qnx6_find_entry() because it might be a long dir_entry with a different format. So stick with the convention of returning an inode number, but rename it to qnx6_find_ino() to reflect what it actually does, and move the call to qnx6_put_page() inside the function which lets us get rid of the res_page parameter.

2024-07-28minmax: simplify and clarify min_t()/max_t() implementationLinus Torvalds
This simplifies the min_t() and max_t() macros by no longer making them work in the context of a C constant expression. That means that you can no longer use them for static initializers or for array sizes in type definitions, but there were only a couple of such uses, and all of them were converted (famous last words) to use MIN_T/MAX_T instead.

2024-07-28minmax: add a few more MIN_T/MAX_T usersLinus Torvalds
Commit 3a7e02c040b1 ("minmax: avoid overly complicated constant expressions in VM code") added the simpler MIN_T/MAX_T macros in order to avoid some excessive expansion from the rather complicated regular min/max macros. The complexity of those macros stems from two issues: (a) trying to use them in situations that require a C constant expression (in static initializers and for array sizes) (b) the type sanity checking and MIN_T/MAX_T avoids both of these issues. Now, in the whole (long) discussion about all this, it was pointed out that the whole type sanity checking is entirely unnecessary for min_t/max_t which get a fixed type that the comparison is done in. But that still leaves min_t/max_t unnecessarily complicated due to worries about the C constant expression case. However, it turns out that there really aren't very many cases that use min_t/max_t for this, and we can just force-convert those. This does exactly that. Which in turn will then allow for much simpler implementations of min_t()/max_t(). All the usual "macros in all upper case will evaluate the arguments multiple times" rules apply. We should do all the same things for the regular min/max() vs MIN/MAX() cases, but that has the added complexity of various drivers defining their own local versions of MIN/MAX, so that needs another level of fixes first.
